Healing an Achilles Heel in DNA Testing

The discovery of mental illness clusters within families has sparked genetic research—but the data has a diversity problem.
78% of current DNA data comes from people of European ancestries, who thus stand to benefit most from related treatment advances, write Anne Stevenson of the Harvard T.H. Chan School of Public Health and Lukoye Atwoli of Kenya’s Moi University School of Medicine.
To fill the gap, US and African institutions launched a massive research effort, recruiting 35,000 people from 4 African countries for DNA testing to find unique genetic differences, and potentially new medicines tailored to people of African descent. Much of the human population migrated from Africa, so the insights stand to benefit people of all ancestries.
